' 6 Claims. (Cl. 29-12s) tween the chest and rolls, but/the invention ismore particularly directed to an insulated aluminum cover for the rolland means permanently attached to the roll coacting with complementalmeans carried by the cover for detnchably securing the cover to theroll.

In connection with the at-workironers of the above character, therespective rolls are provided with a covering of padding material, whichin turn is covered with duck or treated fabric which constitutes theironing surface of the roll and which presents many disadvantages, amongwhich may be noted: that such cover material is stiff and when wrappedaround the roll with the trailing end free, in operation, the latterwill fold over and crease causing the cover to split, thereby notonlydamaging the cover but giving a rough nish to the linen. This type ofcover also permits heat to penetrate-through the pad and to the roll,tending to burn up the pad and effecting a loss of heat, which increasesthe operation cost and slows down production; therefore, the principalobject of this invention is the provision of analuminum cover having aninsulated surface next to the pad and roll which reects heat therefrom,thereby tending to preserve the pad and such structure, increasing thelife of the cover, and giving a smooth finish to the ironed material.vThe covers heretofore in use have been secured to the roll at one end bygluing, which requires considerable time and effort to remove uponWearing out of the cover or because of damage thereto, requiringreplacement with a new cover. Also, at times the gluing permits thecovers to slip, which requires their replacement, and in order toreplace such cover, a complete shut-down of the iron for a considerabletime is necessary. Therefore, afurther important object of thisinvention is the provision of a positive cover-attaching means mountedpermanently on the rolls, and provided with anchoring means engageablewith complemental means carried by the end of the aluminum cover,thereby enabling the cover to be removed and replaced in a few minutes.

InV an ironing machine of this type employing a plurality of ironingrolls, at a point where the dampened andl cold dat-work or linen entersbetween the heated chest, and the padded rolls, the initial rolls inoperation are continuously wet and in a short time become cornpressedand also cease to absorb the moisture, and if the moisture is Vallowedto remain in the flat-Work it causes a rough-dry finish. Therefore,another important object of this invention is the provision ofperforations in the aluminum covers of the initial roll or rolls,depending upon the number of rolls in the particular machine, whichperforations allow the moisture to pass into the underlying pad and dryout, whereby a smooth finish is imparted to the material being ironed. l

A still further object of this invention is the provision 2,762# llPatented Sept. 1,1, 1%956 ice of a novel cover-attaching means and aninsulated vthin f flexible aluminum cover that will go once 'around tocompletely coverthe roll, but the free end of which will remain in placeand impart a smooth nish to the ironed material.

Another important object of this invention is the provision of acovering assembly for dat-work ironer rolls comprising an envelope pad,a exible metal cover for the pad, and interlocking means in connectionwith the roll and metal cover for detachably securing the cover inoperativeposition about the roll. 1

With these and other objects in view,- which will become apparent as thedescription proceeds, the invention resides in the construction,combination andarrangement or" parts, hereinafter more fully describedand claimed,
